Filtro de supressão RF/EMI DeLOCK D-Sub 9 pinos macho para fêmea dourado

The DeLOCK RF/EMI interference suppression filter is a D-Sub adapter with 9-pin male to 9-pin female connections and gold-plated contacts. It integrates broadband low-pass filters to reduce radio frequency (RF) and electromagnetic interference (EMI), helping to maintain stable signal transmission on Serial RS-232/RS-485 lines and on digital and analog I/O interfaces. The adapter is finished in silver and is designed for inline use where D-Sub signal integrity is required.

Advantages

The adapter contains nine integrated low-pass broadband filters that provide RF/EMI shielding for each signal line, lowering noise and interruptions without altering connector form factor. Gold-plated contacts improve contact reliability and corrosion resistance. The 9-pin male-to-female D-Sub layout makes it compatible with standard D-Sub 9 connectors used in serial communications and I/O applications.

Suitable for (tasks / use cases)

• Reducing RF/EMI noise on RS-232 serial connections
• Suppressing interference on RS-485 links
• Protecting digital and analogue I/O interfaces from signal disturbances
• Inline filtering between devices and D-Sub cables in industrial or laboratory setups

Key specifications

• Connector 1: D-Sub 9 pin (male)
• Connector 2: D-Sub 9 pin (female)
• Function: RF/EMI interference suppression with nine low-pass broadband filters
• Contacts: Gold plated
• Colour: Silver
• Brand: DELOCK, MPN: 66476, EAN: 4043619664764

How to use

Connect the male D-Sub 9 pin side of the adapter to the female D-Sub port of the transmitting or receiving device, and attach a standard D-Sub 9 cable to the female side of the adapter. Ensure connectors are firmly seated and screws secured to maintain proper contact. The integrated filters operate passively once the adapter is in place and do not require configuration or power.

Recommendations

Use the adapter inline close to the device or cable entry point where interference is suspected. For best results, avoid placing the adapter near strong RF sources and inspect connectors for corrosion or looseness periodically. If higher attenuation or specific frequency filtering is required, consider a dedicated external filter designed for that frequency range.
